Vector Project - Export annotation format

When you export a Vector Project, the download folder contains JSON files of your annotations. Each image has its own JSON file.

The explanation will be based on the following example:

Annotation JSON in the Vector tool contains 4 main fields:

{
    "metadata": {},
    "instances": [],
    "tags": [],
    "comments": []
}

Metadata

{
    "lastAction": {

    "height": 1080,
    "name": "94573794",
    "projectId": 9425,
    "isPredicted": false,
    "qaEmail": [email protected],
    "annotatorEmail": [email protected],
    "status": "Returned",
    "pinned": false
}

Description:

  • “lastAction”: The user who last edited the image. Edits include changing the class of an instance, adding or deleting attributes, adding point labels, approving or disapproving instances, and moving or scaling instances.
    • “email”: string - The email address of the last user who added or edited an instance.
    • “timestamp”: number - The date and time when the last instance edit was made.
  • "width": integer - The image’s width.

  • "qaEmail": string - The QA’s email address.
  • "annotatorEmail": string - The annotator's email address.
  • "status": string - The image status. It can be: Not Started, In Progress, Quality Check, Returned, Skipped**, or Completed.
